At room temperature you have to compress natural gas to 1000 PSI to liquify it so it is a rather dangerous fuel. It also has a burn ratio of 10:1 while gas is 14.7:1. Gasoline is relatively safe whereas LPG is an explosion waiting to happen.

Perhaps in theory.
I owned a house next door to a taxi company with a fleet of
propane taxis, 24x7, every day including holidays. In 40
years there were no incidents involving fuel. Robberies,
vandalism, storm damage, minor car-taxi crashes but no fuel
problems.

You are wrong again.
Natural gas, often called LNG, may become a liquid under 1,000 PSI. I
don't know and it is of no interest to anyone as LNG is converted to a
liquid by temperature not pressure, -260 degrees(F), and this is done
simply to make it easier to transport in bulk and once it gets to the
end user, say the city gas works, it is vaporized and furnished to
houses at about 1/4 psi, or about 7 - 8 inches of water pressure.

The flammability range of LNG (Methane) in air (21% Oxygen) is
approximately 5.3 to 14% (by volume)

Propane is only one constituent of natural gas and it is deemed a great deal safer. It liquefies at a lower pressure and it is less explosive without the methane and ethane.

Well Tommy if you are calling "natural gas" what comes out of oil
wells then yes propane may be a part of it but if you are calling
"natural gas" what flows through the city or town "gas system" then
you are totally wrong.

What is called in the trade "LPG" Liquefied Petroleum Gas is largely
propane gas but if you are talking about "LNG" Liquefied Natural Gas
then it is largely Methane.

LPG is what comes in small tanks and you use in a cooking stove while
LNG is transported by tanker in a liquid form and used, say in city or
town gas systems as a gas.

If you are going to play the game then you really do need to learn the
names of the players.
